. 42 Claims. (01.197-126) This invention relates to manifolding devices} and in particular, to devices employing copying materials such as ribbons or carbons for making multiple copies of documents, especially those used in connection with typing, adding and tabulating machines and the like.

One object of this invention is to provide a manifolding device employing copying ribbons either alone or with carbon strips having means to prevent the adhesion of the copying ribbons to the multiple paper sheets whereby the ribbons are caused to start moving before the paper sheets or webs begin their motion, and to continue their motion after the paper has ceased moving. Optionally, carbon strips are additionally provided, with appropriate mechanism therefor to cooperate with the ribbons and amplify their action so as to produce a number of copies in excess of the number conveniently produced by the ribbons alone; these carbon strips being either in sheets or in continuous webs.

Another object is to provide a manifolding device wherein the paper sheets and the copying ribbons are moved intermittently relatively to'the typing mechanism so that the ribbons and paper are stationary while the imprint is being made, yet move to new positions after the printing has been completed.

Another object is to provide a manifolding device having a plurality of duplicating or copying ribbons interleaved between a plurality of paper webs, means being provided to prevent the ribbons from moving in the direction'of motion of the webs by adhesion thereto; this adhesion being prevented by causing the ribbons to start their motion before the paper moves, and to continue their motion after the paper stops moving.

Another object is to provide a manifolding at tachment for a. tabulating, adding or similar machine, which prints records, the attachment being connected to the machine in such a manner as to operate synchronously with the machine.

Another object is to provide platen mechanism for interconnecting the manifolding attachment of this invention with the machine to which it is to be attached, this platen mechanism serving as the connection for synchronizing the machine and the attachment.

Another object is to provide a manifolding at tachment for use with a tabulating machine, the attachment havingrineans employing duplicating or copying ribonsqcooperating with the typing already written up'on'the tabulating machine to produce additional copies of the tabulated records,

totalizer thereof for a new typing operation, thedevices being arranged to cause the attachment motor to stop during the time while the printing or typing mechanism of the totalizer causes an imprint upon the paper sheets and copying ribbons. I

Another object is to provide a manifolding attachment wherein copyingribbons are interleaved between the paper webs, a single copy ribbon being caused to be twice interleaved by being passed to and fro between the webs in reverse directions, the ribbon at one limit of its motion having a guide roller or similar means for causing it to reverse its direction of motion.

Another object is to provide a manifolding device having means positively engaging the file punch holes, such as pins upon chains positively driven by mechanism synchronized with the printing mechanism of the machine to which the device is attached, the paper webs or sheets being interleaved by copying or duplicating ribbons traveling in a transverse direction to thedirection of motion of the paper, or by carbon strips.

Another object is to provide a manifolding device having mechanism for the step-by-step feeding of a plurality of copying or duplicating ribbons interleaved between a plurality of moving paper webs, together "with mechanism for synchronizing the feeding of the ribbons and the paper webs with the printing mechanism of the machine in connection with which the manifolding device is employed.

Another object is to provide a manifolding device employing a plurality of copying ribbons which are interleaved between and moved in a direction perpendicular .to the direction of motion of multiple paper webs means being provided to cause the ribbons to automatically reverse their direction of travel when the ribbon reaches a predetermined position, such as when the supply of ribbon on one spool has diminished to a predetermined extent.

Another object is to provide an attachment for a tabulating machine consisting of a plurality of fingers arranged to control and position the master ribbon of the printing portion of the machine so that it may cooperate with additional copying ribbons employed in a manifolding at tachment used in connection therewith.

Another object is to provide a manifolding device having multiple copying ribbons, these ribbons being guided by means mounted upon a movable carriage and interleaved between multiple paper sheets or webs, the carriage in one location being arranged to permit the paper webs to be easily threaded between the ribbons, and in another location to be placed in the printing position, the carriage in the printing position being preferably arranged to put the copying ribbons under the proper tension.

Another object is to provide a manifolding device having copying ribbons caused, in different portions of their length, to move perpendicularly, means being provided to change the direction of motion for this purpose; each ribbon being caused to move from one side of the machine to the other side around a guide, and thence back again across the machine so that a single ribbon ac-' complishes the purpose of a plurality of ribbons.

Another object is to provide a manifolding device having positive feeding means engaging multiple paper webs, as by perforations therein, this positive feeding means being synchronized to be moved by a motor, the operation of which is controlled by connecting mechanism operated by the printing machine in connection with which the device is used, the same mechanism also controlling the motion of multiple duplicating ribbons interleaved between the paper sheets or webs.

Another object is to provide a manifolding device which is pivotally arranged to be swung from an operative to an inoperative position, together with a container mounted on the frame for receiving the paper sheets or webs after they have been printed, with means for holding this con- I tainer in position.

General construction In general, the manifolding device of this invention, as shown in the upper right-hand corner of Figure 1, is an attachment to be used in conjunction with some machine capable of typing or printing a record, especially a numerical record. The main machine ordinarily possesses its ownribbon in connection with its printing type,

and the manifolding device is intended to supplement the action of the main ribbon by providing sheets and required some means for being moved to and froafter acertain length of paper was typed so as to bring the carbon sheets into engagement with an untyped series of paper sheets or webs.

In the manifolding device of the present invention, however, the multiple copies are made by copying or duplicating ribbons interleavedbe tween the multiple paper sheets and traveling in a direction perpendicular to the direction of motion of the sheets or webs. Ordinarily, the

adhesion of the ribbons to the paper prevents the successful use of copying ribbons, where.

these ribbons must move in a direction transverse to the direction of motion of the paper. In the present invention, however this dimculty hasbeen overcome by providing mechanism which causes the copying ribbons to start their motion before the paper webs or sheets commence tomove, the motion of the ribbons being continued for a short period after the paper webs have stopped moving. This provision eliminates the adhesion between the paper webs and the ribbons, and prevents the ribbons from being carried upward with the paper and out of registry with the type bars.

The manifolding device .of the present invention is connected to the mechanism or the machine to which it is attached so that its motor and driving mechanism are synchronized to operate at the proper times with respect to the operation of the machine as a whole. This connection is made through mechanism attached to the left end of the platen, as viewed in Figures 1 and 2, this mechanism controlling the starting and stopping of the motor which feeds the paper webs and moves the copying ribbons. The machine with which the manifolding device is used may be of type and employs cards which are punched with 1 apertures in different positions, according to the data recorded on the particular card. The cards are then fed into the left-hand end of the machine. at the delivery point I, and pass dovmward through the portion 2. At the latter location the cards are subjected to certain mechanism which automatically analyzes the data recorded on the card, this data being addedor otherwise operated upon by mechanism between the portions 3 v of the machine, thetotals appearing in the windows 4 thereof.

After being thus analyzed the cards 5 drop downwardly into a movable holder 6, beneath the portion 2, where they accumulate and cause the holder 6 to move and accommodate moreoards. Counterweights 1 assist in regulating the position of the holder 6. A motor 8 serves to operate the tabulating machine shown, in response to the depression of the operating keys 9, II] or H. The various mechanism sections 3 are interconnected by shaft portions l2, terminating in a portion l3 which enters the printing or listing section [4 of the machine; This section is likewise controlled by the starting push button I 5, the stopping push button l6 and the resetting push button H. A clutchshaft 'l8, operated by a hand lever I 9, serves selectively to connect or disconnect the printing section l4 from the remainder of the machine so that the machine may be operated either to tabulate the results without printing, or to print the results as well as to tabulate them.

These type bars 20 are operated by bars 20 to furnish the master record of the machine. The master ribbon 2| is connected at its opposite ends to spools 22 and .23, supported on the shafts 24 and 25, and regulated as to their reversal by the T-lever- 26 (Figure 2). The latter is pivoted, as at 21, and carries portions on its opposite ends engaging the ribbon and caused to move to and'fro when the end of the ribbon is indicated bya. knot, or.other projection. The vertical part of the T-lever 26 is joined to a connecting rod 28, which serves to control mechanism for c'ausing'the spool 22 or the spool 23 to be driven according to the position of the T-lever 26.

The master ribbon 2| is guided at suitable intervals in its path by the guide rollers 29. The shafts 24 and 25 for carrying the ribbon spools 22 and 23 are supported in a framework, generally designated 38, and supported by the printing section l4. A cover plate3| serves to inclose the printing mechanism, and is provided with a guide plate 32 having downwardly extending ribbon fingers 33 for holding the master ribbon 2| in position and preventing it from rising or falling.

The machine is likewise provided with a platen 34, mounted in a suitable frame having end plates 35 and 35 and tie rods 31 (Figure 2). The platen 34 is provided with gripping rollers 38 mounted upon the arms 39, attached to the gripping roller shaft 48 and arranged to be moved into or out of engagement with the platen 34 by the action of the hand lever 4| connected to the operating shaft 42 thereof. When the hand lever 4| is in the lower position shown in Figure 2, the gripping rollers are-out of engagement with the platen 34. If, however, the hand lever 4| is raised it causes the gripping rollers 38 to engage the platen 34. When used with the manifolding device of the present invention, however, the gripping rollers 38 are maintained out of engagement with the platen 34 so that the platen itself exerts no aligning function. The alignment of the various paper forms is provided by mechanism within the manifolding device itself and not within the machine to which the device is attached.

The platen 34 is mounted upon the platen shaft 43 (Figure 2) and rotated manually by the knobs 44 and 45. The right-hand end of the. platen shaft 43 is'driven by gearing, subsequently to be described, and communicating power thereto from themanifolding device shown in the upper part of Figure 2. The left end of the platen shaft adjacent the end plate 35 carries the mechanism by which the machine and the manifolding device are interconnected and synchronized. The platen 34 may be moved to and fro laterally, as is usual in such machines, and when it is so moved the manifolding attachment moves with it. This motion is provided in order to adjust the position of the printing upon the particular paper form or web. The platen 34 is cut away at its ends to provide slightly reduced diameter portions 46, which serve to permit the copying ribbons to more closely approach the platen, as will be described subsequently.

The left end of the platenshaft 43 carries a disc 41 (Figure 18) having pins 48 surrounded by coil springs 49 bearing against the end of the platen 34. By this means theplaten .34 may be adjusted longitudinally along its shaft 43, while the disc 41 remains stationary. Secured to the disc 41 is a ratchet wheel 58 by which the platen 34 may be revolved step by step by the usual pawl and ratchet mechanism. This mechanism is shown only incidentally because it is not made use of in the operation of the manifolding device of this invention. As previously stated, the gripping rollers 38 are held out of contact with the platen 34 during the operation of the manifolding device, and hence, the operation of the platen ratchet 58 will have no effect upon the feeding of the paper webs, this being controlled by means within the manifolding device.

The pawl the upper end of which is shown in Figure 18, is pivoted on the pin 52 and is, in turn, mounted upon the arm 53 pivoted on the platen shaft 43. The pawl 5| is held in engagepin 52, carries a. pin 55 which is engaged by a forked arm 56 for raising and lowering the pawl arm 53 and the pawl 5| as the forked arm 56 is moved up and down. The forked arm 56 is attached to a bracket 51 secured to the pivot shaft 58, extending between the platen end plates 35 and 36. Through the outer end of the bracket 51 passes the cross shaft 59, which runs parallel to the pivot shaft 58 and is capable of being moved up and down around the pivot shaft 58.

As the cross shaft 53 moves up and down the bracket 51 and the forked arm 56 pivot around the pivot shaft 58. The outer end of the forked arm 56 engages the pin 55 on the pawl arm 53, causing the pawl 5| to move up and down and move the ratchet 58 one notch for each stroke of thecross shaft 59. A roller 68, carried by the arm 6|, serves as a detent engaging the ratchet 58, the arm 6| being pivoted around the pivot pin 62 supported by the stud 63 mounted on 'the platen end plate 35. The lever 64 carries a projection 65 which engages the pawl 5| to cause it to move selectively through a distance representing either one or two notches of the ratchet 58, thereby providing for single or double space motion of the platen 34. The spring 66 serves to hold the lever 64 in either of its adjusted positions, whereas the spring 61 holds the roller 68 of the arm 6| in engagement with the ratchet 58. This platen rotating mechanism (Figure 18), as stated above, is not employedrwhen the manifolding device is in use because it is operated ineffectively by reason of the fact that the gripping rollers 38 are out of engagement with the platen 34.

Mechanism for synchronizing manifolding device with printing machine The cross shaft 59 is given its up and down motion by a link 68 pivoted thereto at its upper end (Figures 17 and 18), the lower end being pivotally connected, as by the bolt 69, to the rocker arm 18 (Figure H). The rocker arm 18 is pivotally supported. at an intermediate point by the bolt H, and has a connecting rod 12 secured to its outer end, as by the bolt .13. A slot 14 in the connecting rod 12 provides an adjustment whereby, the position of the rocker arm 18 may be varied with respect to the connecting rod 12. The connecting rod 12 is operatively connected to the mechanism within the printing section H of the machine and moves up or down in response to the action of this mechanism. The pivot bolt H is mounted upon the frame of the printing section I4, assisted by the supporting bracket 15. Accordingly, as the connecting rod 12 moves up and down intermittently in synchronism with the printing mechanism of the machine, the link 68 will likewise be moved up and down to actuate the pawl 5| and move the platen 34 either through single notches or double notches of the ratchet 58, as controlled by the setting of the lever 64. Figure 17 shows the link 68 in its raised position, whereas Figure 16 shows the link 68 in its lowered position.

Mounted for reciprocation vertically on the platen end plate 35 is a J-shaped member 76 (Figure 17), having its lower end 11 extending beneath the platen end plate 35 and forked to engage the cross shaft .59 (Figure 15). The slot 18, cooperating with the pin 19, guides the J- shaped member 16, in its vertical reciprocation, and the spring 88 connected between the pin 19 and the pin 8|, near the lower end of the member 16, urges the latter into.an upward position and accordingly urges the cross shaft 59 into an upward position. Mounted on the upper right-hand comer of the J-shaped member 16 is a stud 82, which is engaged by theforked end 83 of the lever 84. The latter is pivotally mounted upon the platen shaft 43 (Figures 16, 17 and 18), and at its opposite endis provided with teeth 85 adapted to mesh with the corresponding teeth of a pinion 86, rigidly secured to the lever 81. The latter is pivotally mounted on the pin 88, supported by the supporting arm 89 mounted on the platen end plate, as by the screws 90. The-latter also support a guide plate 9|, serving to guide the motion of the ratchet operating lever 92. The latter is pivoted at its upper left-hand corner around the pin 19 and is provided with a cam surface 93 adapted to engage the pin 8| on the lower part of the J-shaped member 16.

By moving the ratchet operating lever 92 from its upper position (Figure 17) to its lower position (Figure 16) the J-shaped member 16 may be moved up and down, and with it the cross shaft 59, thereby operating the pawl 5| to move the platen ratchet 50 by'single or double notches, according to the setting of the lever 64. At the same time, however, it will be seen that the operation of the lever 84, through its engagement with the stud 82 on the 'J-shaped member 10, will cause the lever 81 to move outward into the position shown in Figure 16 by reason of the intermeshing of the teeth upon the end of the lever 84 and the pinion 86. The lever 81 is connected to the motor operating switch and clutch of the manifolding device, in a manner subsequently to be described and in such away that when the lever 81 is in its inward position, shown in Figure 17, the motor is energized and the paperfeeding mechanism caused to operate. When the lever 81 is in its outward position, shown in Figure 16, however, the manifolding device motor is deenergized and the paper-feeding mechanism accordingly halted. Thus, as the platen ratchet 50 is operated manually by the hand lever 92 the manifolding device motor is T automatically disconnected. Similarly, when the link 68 is moved up or down by the action of the rocker arm 10' during the printing operation, the J-shaped member I6 is likewise moved up and down, and the lever 8'! moved in and out to energize and deenergize the manifolding device motor, respectivelv, but the hand lever 92 remains motionless bec'ause it merely has a contacting engagement between its cam surface 93 and the pin 8|. By this means the motor of the manifolding device is causedto operate in synchronism with the printing section I 4 of the machine.

M am'foldz'ng device frame and drivingmechanism paper forms before they are ready for printingf The paper webs. generally des gnated 99. are folded in a zigzag manner in the pack 98. The paper webs 99 pass upward through a cutaway portion or slot I in the table top 95 (Figure 6), over a rod IM and into engagement with the platen 34. The rod MI is supported by the U- shaped frame upright I02, secured t?) the table top 95 by the bolts I03. The rod I 0| is engaged by its opposite ends by the hand wheels I04, which serve selectively to halt or release the manifolding device supported thereby.

The manifolding device is supported by frame side members I05 (Figures 4 and 5), having cross arms I06 interconnecting them for bracing purposes and for supporting a container- I01 for receiving the printed paper forms. The container I01 is shown as a basket, but may "consist of a box or other suitable receptacle for the paper webs after they have been subjected to the printing action of. the printing section Id. The side members I05 serve to support the entire manifclding device and are pivotally mounted upon the shaft IOI in such a manner that the .device may be placed in its upright or operative position, shown inrsolid lines (Figures 5 and 6), or

in its inoperative inverted position, as may be desired. When so inverted the frame side members I05 rest upon resilient blocks I08, mounted upon the supports I09 on each side of the table top 95, as by the bolts I I0. Mounted on the lefthand side member-I05 is a bracket I, having a resilient pad- II2 serving to support the motor II3 for driving the manifolding device. The

drive shaft H4 is joined by the resilient connection 5 to the motor drive casing 6. Beyond the resilient connection II5 the drive shaft continues in a portion II 'I (Figure 6). The latter enters the motor drive casing IIS and carries on its lower end a worm II8, the worm- I|8 meshing with a worm gear II9 (Figure 6).

The worm gear H9 is provided with clutch mechanism for selectively connecting and disenergizing the motor 3, the switch and clutch 4 being simultaneously operated by the operating lever I2I extending downwardly from the casing IIG (Figures2and 6).

The operating lever I2I is provided with a projecting pin I22 adapted to be engaged by the corresponding notch I23 in the lever 81, mounted on the end plate of the platen (Figures 16 and 1'7). Accordingly, when the lever 81 moves to and frov as the link 68 moves up and, down, the motor 3 will be energized or deenergized and connected with or disconnected from the output shaft I20. 1 The mechanism within the casing I l Ii is so arranged, as disclosed in the above mentioned patent, that the clutch will be opened so that the motor will spin to a stop, when the operating lever is moved by the motion of the lever 81. At the same time the operating lever carries a tab I24, whereby it may be operated manually.

(Figure 2). The mechanism within the casing H6 is also so arranged that it executes a complete cycle of rotation regardless of when the lever 'I2I is released, so that the paper sheets or webs 99 will be fed only through whole spaces and not partial spaces, thereby preventing one set of typing from partially overlapping another set.

Paper feeding mechanism The frame side members I05 are interconnected bya cross bar I25 (Figure 3), carrying frame uprights I20. These uprights are of channel or U-shap'ed cross'section, and at their upper ends carry slotted brackets I21 inserted therein, and held in position by the bolts I28 passing through the slots I 29. The brackets I 21 at their upper ends are bored to rotatably support the shaft I30. The latter is provided with a plurality of
